Abstract
A new gas chromatographic method reliable in the microgram range, was developed to measure ETU residues in various crops. Contrary to previously published procedures, this new method does not require prior derivatization of the ETU. The limit of sensitivity was shown to be 0.01 ppm using the flame photometric detector, FPD (sulfur mode, 394 nm).
摘要
开发了一种在微克范围内可靠的新型气相色谱法，用于测定各种作物中的乙撑硫脲残留量。与先前公布的方法相反，这种新方法不需要对乙撑硫脲进行预先衍生化处理。使用火焰光度检测器（FPD，硫模式，394nm）时，灵敏度极限为0.01ppm。
